  • Patent number: 6676286
    Abstract: The component (1) for a static mixer(100) is manufactured by cutting and forming or by stamping out of a planar material strip (10). It extends in a longitudinal direction (11) given by the material strip. The component has transverse segments (2) arranged at intervals transversely to the longitudinal direction (11) that lie in a central plane (12) of the component (1) after forming or stamping. Strip fields (30) are located between the transverse segments (2), correspond to a line pattern made by the cutting or stamping and include longitudinal strips (3), i.e. strips (3) extending in a longitudinal direction. The transverse widths of the strips can be variable. For each strip, half-strips (7, 8′; 8, 7′) can be respectively distinguished with respect to the central region (6) of the strip field. The half-strips are bent out of the central plane (12) by the forming or stamping, and each form a bending edge with respect to the transverse segments (2) at the base lines (32).

  • Patent number: 6575617
    Abstract: A static mixer includes profiled layers which are arranged in a ring space and which contain mutually crossing flow channels which are inclined relative to a central axis. A fluid mixture is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis. Each layer comprises equivalent channels which extend on an inner or outer side of the layer over at least approximately equally long distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels.

  • Publication number: 20010038576
    Abstract: The static mixer comprises profiled layers (1, 2) which are arranged in a ring space (3) and which contain mutually crossing flow channels (14, 24) which are inclined relative to a central axis (z). A fluid mixture (4) is to be transported in the axial direction in the presence of a mixing action. Each layer extends over a surface which forms a closed or largely closed periphery transverse to the axis (z). Each layer comprises equivalent channels (14, 14′, 24 and 24′ respectively) which extend on an inner or outer side of the layer over at least approximately equally long distances from a first to a second cross-section of the ring space, so that each channel imposes an azimuthal velocity component (40, 41) onto the fluid mixture which flows through it which is substantially equally large for all equivalent channels.
